I have a site for classifieds wich expires after a preset amount of days. The question is: What is best for Google? 1.To give him a 200 ok header with the same page in wich I have a meta NOINDEX 2.To give a 404 Not Found 3.To make a 301 redirect to main domain
I actually have this same issue on several of my sites. I have built logic to provide a link to a possible alternative match when the listing expires. I do not remove the page unless itís older than 30 days. You should always produce a 404 if you cannot reveal a themed alternative.
Its just bad for the user and the search engine will not care for a 301 from one subject to another.
So your advice is to make a 301 redirect of expired page to a themed page? I can do that becouse each classified ad is posted under a category and in case the ad expire users will go to that category main page. Other opinions please?
